The weights of the blocks A, B and C, shown in figure worth, 89N, 44,5 N and 44,5 N, respectively. The blocks are initially at rest. Knowing that B travels 2,44 m in 2s, determine (a) the module of F and (b) the tension on the rope AD. Discard the masses of the pulleys and friction.
Answer:
(a) 7,37 N
(b) 92,7 N
My solution
Block B
ZFy = mB . aB
T - F - mB.g = mB . aB
Block C
ZFy = mC . aC
-mC . g + T = mC . aC
aB = -aC
